Explos
Explosives are chemical compounds or mixtures designed to release large amounts of energy rapidly, producing heat, gas, and a high‑pressure shock wave. The resulting blast can fracture, displace, or remove material and is exploited in mining, construction, demolition, and military applications. In common usage, the term covers energetic materials (explosives) and the fast-acting energetic devices used to break substances.
Classification: Explosives are commonly divided by their energy release mode. High explosives detonate, generating a supersonic
Mechanism and effects: The detonation or rapid burning produces a blast wave, overpressure, heat, and fragmentation.
History: The oldest energetic substances were developed with gunpowder in ancient China. The 19th century saw
Applications: Explosives are used for rock blasting, tunnel and road construction, quarrying, and demolition of structures.
Safety and regulation: Handling and storage are tightly regulated, requiring licenses, trained personnel, and compliant facilities.
